Porcine γδ T cells have two levels of TCRγδ expression. Whereas TCRγδ(med) cells are mostly CD2(+)CD8(-) and CD2(+)CD8(+), TCRγδ(hi) cells are highly enriched for CD2(-)CD8(-). This distribution is independent of bacterial colonization and it is already established in the thymus prior to export of γδ cells to the periphery. Sorting and cultivation experiments revealed that CD2(-)CD8(-) γδ cells...

China is a large agricultural country that produces amount of crop straw every year. Thus, the development cost-effective and economic application invasive plants warranted. Biochars derived from have been proven to be promising for adsorbent materials. However, less studies focused on biochar different types as under same conditions compare their adsorption performance. Here, we characterized ...

This paper examined the competitive removal of metal ions from quaternary aqueous solutions containing Ni2+, Mn2+, Cr6+, and Cd2+ using adsorption on both acid-modified unmodified activated carbon. Activated carbon (AC) was oxidized with nitric acid, in granular (AGC) powder (APC) forms, tested for an solution. Surface oxidation led to a reduction BET surface area HK pore width increase intensi...

In this work, innovative biosourced polyimide polymers were derived from novel combinations of monomers (Isosorbide, 6-FDA and amine cardo). These obtained with satisfactory yields by polycondensation different percentages isosorbide (from 100% to 0%). The synthesized polyimides had number average molecular weight in the 17,600–22,000 g/mol range, they stable well above 451 °C (5% loss N2). gla...

Soil contaminations by heavy metals near oilfields have been widely reported and are causing great concern. Thus, it is highly desirable to develop cost-effective materials methods avoid metal residues contaminating soil food. An effective, environmentally friendly, inexpensive remediation material for metal-polluted was designed prepared using biochar (BC) combined with humic acid (HA) resulti...

Cadmium ions (Cd2+) have been reported to accumulate in bovine tissues, although Cd2+ cytotoxicity has not been investigated thoroughly in this species. Zinc ions (Zn2+) have been shown to antagonize the toxic effects of heavy metals such as Cd2+ in some systems. The present study investigated Cd2+ cytotoxicity in Madin-Darby bovine kidney (MDBK) epithelial cells, and explored whether this was ...

The present work describes the synthesis of copper(II) oxide nanoparticles (NPs) with high surface area (52.11 m2/g) and its Ni(II) adsorption efficiency from contaminated water at room temperature. Copper (II) NPs are able to remove as 93.6 per cent 93.7 using 500 ppb & 1000 initial concentration nickel near-neutral pH respectively. CuO is very much effective more than 75 over a wide range...

Low levels of CD2 have been described on subsets of monocytes, macrophages, and dendritic cells. CD2 is expressed on about one-third of circulating monocytes, at levels one-half log lower than on T or NK cells, representing 2-4% of PBMC. FACS analysis of CD2+ and CD2- monocytes revealed no significant difference in the expression of adhesion molecules (CD11a/b/c), class II Ags (HLA-DR, -DQ, -DP...

T cells may be activated either by the antigen-specific T cell receptor (TCR)-CD3 complex or the cell surface receptor CD2. A natural ligand for CD2 has been found to be lymphocyte function-associated antigen 3 (LFA-3), a widely distributed cell surface glycoprotein. To investigate the interaction of these two pathways, we have expressed the cDNA encoding the human CD2 molecule in a murine T ce...
